Amazon India — money not refund

18/04/19
I ordered a product from amazon app on 10th april 2019 for which i paid ₹10999 through my debut card no.[protected]. Due to some reason i cancelled that order the same day that is 10th april 2019. I was supposed to get refund with 3-5 working days according to the amazon refund policy. After 5 days when i contacted them and told them about not getting refund they told me that the refund has been initiated from there side ref. No.[protected] but the amount is not added to my account. The bank denied to do any such thing and said we don't have that facility. Please resolve this issue as it is... My ac [protected]
